HYDROCARBON SOLDERING INSTRUMENT.

Specification of Letters Patent.

Patented Feb. 2, 1915.

Application filed June 19, 1914. Serial No. 846,119.

To all whom it may concern:

Be it known that 1, JOHN N. KUoEa i, a citizen of the United States of America, residing at Cedar Rapids, in the county of Linn and State of Iowa, haveinvented certain new and useful Improvements in Hyof which the following is a specification.

This invention relates to new and useful improvements in hydro-carbon soldering instruments.

The primary object of this invention is to provide a soldering instrument in the form of a unitary device and providing a soldering point heated by the gaseous burner of the instrument.

A further object is to provide a portable fuel tank burner and soldering iron in which the iron is adapted to be heated by a vapor burner from liquid fuel supplied under pressure from the tank.

A still further object is to provide a hydro-carbon heated soldering point that may be employed for doing over-head work.

Another object of the invention is to pro vide in a hydro-carbon soldering instrument, an adjustable burner that may be moved toward or away from the needle valve that controls the fuel supply, whereby the air supply may be varied at will and the action of the burner thereby regulated.

Still another object is to provide a hydrocarbon soldering instrument with a readily removable burner whereby the device may be quickly converted into a blow torch, of branding or marking device by the substitution of a tube, branding or marking iron as desired.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views :Figure 1 is a side elevation of the device, parts being broken away. Fig. 2 is a top plan view upon an enlarged scale of a portion thereof with parts broken away. Fig. 3 is a transverse vertical sectional view taken upon line TIL-III of Fig. 2. Fig. 4: is a central longitudinal sectional view taken through the burner valve. Fig. 5 is a transverse sectional view taken upon line V-V of Fig. l.

Fig. 6 is an enlarged horizontal sectional view of the feed chamber end of the fuel tank. Fig. 7 is a transverse vertical sectional View of a modified form of burner casing, and, Fig. 8 is a fragmentary longitudinal sectional view of the same.

Referring more in detail to the drawings, it is to be noted the device is adapted to employ any form of volatile fuel such as the well-known hydrocarbons including gasolene; a supply thereof is designed to be contained in the can or tank 10 which is supplied with any desired form of air pump 11 for placing the contained fluid under pressure.

The tank is provided with a dome-shaped end 12 which is secured to a handle 13 preferably formed of wood or other suitable material adapted to. prevent excessive heating which would thereby hinder the grasping of said handle when using the instrument.

The dome end 12 has an inner chamber 14: which is separated by a disk, diaphragm or partition 15 from the main chamber 16 of the tank, while outwardly converging pipes 17 are tapped through the partition 15 to effect communication between the chambers 16 and lt for the passage of the combustible fluid toward the central opening 18 of said dome end, which opening receives the fluid outlet pipe 19 extending through said handle 13 and terminating with one open end slightly spaced from the partition 15 and within the chamber 14:. The burner supply pipe 19 extends outwardly from the handle 13 and is provided with a downwardly curved portion 20 terminating in a dome disk 21 having an outwardly projecting flange 22 for securing a cylindrical open ended burner casing 23 thereto by means of the screws 24. The burner casing is preferably provided withas many perforations 23 as may be necessary to supply suflicient air to provide complete combustion. A Y- shaped burner tube 25 has an upwardly bent arm 26 secured in the central axial perforation 27 of the disk 21 by means of the screw 28. The branching members of the Y-tube 25 have closed ended burners 29 secured therein spaced apart within the casing 23 and provided with transverse slots 30 upon their upper sides for purposes of ignition. A valve casing 31 has a shank 32 screwthreaded into the pipe 20 with the inner bore fuel Which iswithin the chamber-"1e finder ed during the use opposite end communicating with the cen tral boreBh 0t the pipe 2 0, which .bore 36 communicates with the channel ofthe fuel,

supply pipe 19. The casiii'g 31 is provided with an inner chamber 37 .communicating with the berets fand having an outlet 38 nuthe fluid-fuel, which oiitlet is controlled by the needle "valve 39, the out 1e; being n direct aliiiein'erit with the open end of the "bui h er tube arm'QG. With this form {or 'const'ructiomdt will {be appai ent that byqpla'cing ith'e gasolene or other fluid tli'e, fdesi1 e'cl 'air pressure by fhie'a hs of the pump 1 1 an e enin g of the needle valve 39 will allowthe'a'ir pressure "to force thefiuid thrdi-i 'gh itlie pipe 117 fdr partially filling the chamber 14: j'aiid {then passing through the pipe 19 aiid bore 36 and "thence through the looped pipe '35 akiid the bores '34: and '33 to the valve 'c'asiii'g 37 "to he ejected thrhii-gh the valve opening 38 as controlled by the valve 39 tindinto the burner Y-tiih'e f for "supplying the hurner pipes 29 with the fluid fuel.

"A' fu'el receiving socket 40 i theenlarged end 41 of the pipe "20 is adapted to reeeiv'e a email *quaiitity'of the hydrocarbon which upon lcfe'ing ignited supplies the initial heat to'th'e burner for starting thesarne afterthe usual "manner of [the gasolene torch, while the looped tube 35 serves as -a vaporizing coil during the operation "of the burner, the vaporized fluid burhing at the slotted outlets 30, it being of vaporized -fiuid through the valve opening ,38 to the burner is regulated by the needle valve '39. The soldering point 42 is secured "the upper portion df'thef c'asing "by means "of a set "screw 43 projecting through ,thefslot 44 got the casing and engaging the soldering point. It will thusib'e apparent that'fa con tin'uous lie'atingYof the point 4c2'iiia'y-be" eil'ectof the soldering poiiit wliiletheidexiiee i t'ical position, *with the point uppermost in operating upon "elevated objects which is made possible by the chamber 14L allowing such' a position of the instrument to position the end "of the meet "pipe 19 beneath the fluid while thawing, an entrance of 2111- throughthe pipe 17 an'd at a pointremoved from the open outleten'd'of'said pipe, The combustion "fluid enters "the chamber 14 through the 'pipe '17 when 5 the instrument is positioned otherwise than *inhsu'ch upright position; 'Itjis also noted thatif desired to heat theeiztrenfie' point of the "soldering f iron 42 to "a greater degree, the iron '42 "may be slid inwardlyto a greater extentwithin the nderstood that the supply inaybe employed in a ver sired in. its position therein. A foot 45 is ,provided upon the bottom-of the valvefmember 41 and 'adaptd to maintain the instrument upright when positioned upon a support.

In Figs, 7 and 8, a modification is shown in which the vaporizing tube 35 is dispensed with, and in 'li'eu'of s'uch construction, I provide the disk or head 21 with an interior lug 50 positioned. beneath 'Y-membe of the burner Where it will be Slill j titQd to the flame from a jet opening in. said her.
